This option is useful when multiple adapters are present in the system,
and the PCI Device ID, PCI Bus number, and PCI Device/Function
number for each adapter need to be known.
4.3.2.9 Using the Width Option
•
Syntax: width=[targetIDlist] or
wide=[targetIDlist] or
wid=[targetIDlist]
•
Default value: on
•
Valid entries:
narrow = 8 bit data bus
wide = 16 bit data bus
off =
8 bit data bus
on = 16 bit data bus
8 = 8 bit data bus
16 = 16 bit data bus
max = Adapter maximum width
•
Function: Sets bus width negotiations for specified targets.
This option allows you to disable support of wide SCSI when using a
wide SCSI controller. Set this option to narrow, off, or 8 to disable a wide
SCSI device when an 8-bit SCSI cable is connected on the bus between
the wide SCSI host adapter and the wide device. This type of connection
prohibits the transfer of wide data.
If this option is set to narrow, off, or 8, the wide device still works, but all
data transferred to or from the device is narrow (8 bit). The driver does
not initiate a wide SCSI transfer request negotiation. Alternatively, to
enable support of wide SCSI transfers, set this option to wide, on, or 16.
